Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189164, here are decompositions:

13 + 189151 = 189164
37 + 189127 = 189164
97 + 189067 = 189164
103 + 189061 = 189164
181 + 188983 = 189164
211 + 188953 = 189164
223 + 188941 = 189164
307 + 188857 = 189164

Showing the first eight; more decompositions exist.
